An insert apparatus for protecting a curved inner surface within a passageway from abrasion during an abrasive machining operation is disclosed. In various embodiments, the insert apparatus includes a shield having a shell shaped to match a curved portion of the curved inner surface of the passageway and a shaft having a first end connected to the shell and a second end connected to a member configured to maintain the shaft within the passageway and the shell positioned against the curved inner surface during the abrasive machining operation.

A masking tool system includes a first masking body and a second masking body. The first masking body includes a bore passing through a portion of the first masking body and a first sealing element disposed on a first end of the first masking body. The second masking body includes a bore passing through the second masking body and a second sealing element disposed on a first end of the second masking body. The system may also include a rod configured to pass through the bores of the first and second masking bodies and to secure the first and second masking bodies to a metallic article placed therebetween. A diagonal length of the masking tool system induces a wobbling rotation during processing.
